Subject: Patches to support Cogent EM110 network card.
Sender: owner-hackers@FreeBSD.ORG
X-Loop: FreeBSD.org
Precedence: bulk

The following patch adds support for the Cogent EM110 PCI 10/100 Mbit
ethernet card to the existing de interface driver.

All this does is recognize the new EM110 ID code and then uses the EM100
driver code.

This patch has been tested and works on:
	2.1.5-RELEASE
	2.1.6-RELEASE
	2.2-BETA

This patch changes /usr/src/sys/pci/{dc21040.h,if_de.c}

To apply this patch, save it in a file, say, /tmp/em110.patch,
cd to /usr/src/sys/pci, and do 'patch < /tmp/em110.patch'.
Build a new kernel and you're done.
